Preheat the Oven :Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly grease it.
Prepare the Crescent Rolls : Open the can of crescent rolls and separate the dough into triangles along the perforated lines. Spread a generous teaspoon of Nutella onto the wide end of each triangle, leaving a small border around the edges.
Roll and Seal : Starting at the wide end, gently roll each triangle toward the pointed tip, encasing the Nutella inside. Place the rolled crescents on the prepared baking sheet, with the pointed tips facing down to prevent unrolling during baking.
Bake : Bake in the preheated oven for 10–12 minutes, or until the crescent rolls are golden brown and puffed.
Garnish and Serve : Remove the rolls from the oven and let them cool slightly. Sprinkle with powdered sugar for a sweet finish. Drizzle melted chocolate over the top for an extra chocolatey touch. Sprinkle chopped hazelnuts for added crunch and flavor. Serve warm and enjoy the gooey, chocolate-filled goodness!
